A heater is rated at 1200 watts for a 120-volt source. If two heaters are connected in parallel across the 120-volt source, the current in amperes drawn from the source is
A) 5.
B) 10.
C) 20.
D) none of the above.

Question

Quizplus · Accepted Answer

The current drawn by one heater can be calculated using the formula $I = \frac{P}{V}$, where $I$ is the current, $P$ is the power, and $V$ is the voltage. For one heater, $I = \frac{1200}{120} = 10$ amperes. When two heaters are connected in parallel, the total current drawn is the sum of the currents through each heater, which is $10 + 10 = 20$ amperes.
